THE MOLLUSCA HEDLEY. 497 



Reported by Schmeltz from Samoa, Fiji, and Rarotonga ; by 

 Melvill and Standen from Lifu ; and represented in this Museum 

 from New Caledonia. 



LUCINA DIVERGENS, Philippi. 



Reeve, Conch. Icon., vi., 1850, Lucina, pi. vii., spp. 33, 37, 38. 



Common on the lagoon beach. 



Prof, von Martens has pointed out* that Philippi's name enjoys 

 two month's priority over the better known L. fibula, of Reeve. 

 He refers to it from Samoa and Fiji, and Melvill and Standen 

 from Lifu. Material in this Museum show it to extend south 

 along the Australian coast to Newcastle, New South Wales, and 

 also to the Ladrones, New Hebrides, and New Caledonia. 



LUCINA OBLONGA, sp. nov. 



(Fig. 51). 



Shell small, but thick and strong, ovate, very inequilateral, in- 

 flated. Colour, one specimen is white, the other pink. Sculpture 

 the umbones are smooth, the remainder closely and rather 



Fig. 51. 



irregularly covered with numerous, raised, strong, concentric, ribs, 

 narrower than their interstices ; faint radiating sculpture is barely 

 visible in these interstices. Beaks prominent and much incurved. 

 Lunule large, sharply impressed, sculptured by a faint continua- 

 tion of the concentric ribs. Dorsal surface wanting the depression 

 which characterises L. seminula and its allies. Interiorly the 

 margin is most minutely crenulated. Length 3 ; height 3'75 mm. 



Two valves from the lagoon beach. 



Allied to L. congenita, Smith,! from which it differs by being 

 narrower in proportion to height, more densely ribbed, and more 

 inequilateral.

 Sowerby, Conch. Icon., xviii., 1872, Corbis, pi. i., sp. 1.

 Standen from Lifu. It is in this Museum from Port Curtis, 

 Queensland ; New Caledonia ; and Tonga.
